No Flash, No Java, No Websocket, No Bullshit.

This is a very lightweight Speedtest implemented in Javascript, using XMLHttpRequest and Web Workers.

Try it

Take a Speedtest


Only modern browsers are supported (IE11, latest Edge, latest Chrome, latest Firefox, latest Safari)


  • Download
  • Upload
  • Ping
  • Jitter
  • IP Address
  • Telemetry (optional)


  • A reasonably fast web server with PHP (see for details and use without PHP)
  • Your server must accept large POST requests (up to 20 Megabytes), otherwise the upload test will fail
  • It's also better if your server does not use compression, but it's not mandatory

Quick installation videos

Also, here's an example config on Ubuntu 16 LTS
